A polarizer, a polarizer, a color film substrate, a display panel, and a method of conducting away electrostatic charges are disclosed. The polarizer includes a transparent conductive film layer where the transparent conductive film layer is added with a conductive material, and when the polarizer comprising the transparent conductive film layer connects to a ground, the conductive material that is added to the transparent conductive film layer enables the polarizer to conduct electrostatic charges away from the polarizer to the ground.
